I'm building a new engine and want to know how it factors in.
First: C. Cars with a throttle plate area of less than 0.65 mm2/cc : Deduct 12% of
actual displacement.
![Question :?:](./images/smilies/icon_question.gif)
-I have, currently, an 1835cc engine with Two 40mm throttle plates. I can't seem to make this math work.
With the strokes available I can build a 2210cc engine using the same carbs. But with this factor, if it applies, dose it give me that -12% making it a 1945cc engine keeping me in P3?
Also what or where is: Sec. 2.C.4 (DOT tires)
-Not that I'm going to base my engine on this but I'd like to know.
PREPARED 1 – Cars with a displacement of 4501cc to 8000cc.
PREPARED 2 – Cars with a displacement of 2201cc to 4500cc.
PREPARED 3 – Cars with a displacement of 1601cc to 2200cc.
PREPARED 4 – Cars with a displacement of 1600cc and less.
Thanks, Evan
